Conclusion: The Only Game in Town

I keep feeling like Fractal Design is what would happen if Corsair were a European company. They share a lot of the same strengths, but they also share a lot of the same weaknesses, and that's fairly evident with the Define Mini. One thing Corsair consistently does better, though, is convenience. Their cases are typically much easier to build in and make a lot of allowances for the end user.

The Define Mini isn't a bad enclosure by a longshot. 21 pounds for a micro-ATX case seems a little bit much, but this is a lot of steel being used to dampen noise in addition to the acoustic foam. That makes the case both sturdy and capable of containing noise. The white trays and white expansion slots continue to be signature for Fractal Design and reliably sturdy and secure, the lighting is minimal and attractive, and it's frankly a nice case for the $99 price tag.

Where I think things start to fall apart for the Define Mini is its thermal performance. Liquid cooling in general is an excellent avenue for getting good cooling performance for internal components without generating a ton of noise. This is something that makes the Nanoxia Deep SIlence 1 such a strong contender, but unfortunately the Define Mini misses the boat. That wouldn't be so bad if the case was a solid performer with air cooling, but the included fans at least seem to be pretty inefficient. It's difficult for me to actually peg exactly why the Define Mini is such a weak performer where thermals are concerned, but it is.

I don't think all is necessarily lost with the Define Mini. It has some very strong points to its design and a smart builder could produce a competitive machine with it. The noise dampening does a fantastic job of keeping the system quiet, too. There are just missed opportunities here: a couple of allowances here and there for liquid cooling solutions could go a long way. Alternatively, better fans (probably ones comparable to Nanoxia's) or even bigger fans might be the order of the day. You're not getting a 140mm exhaust fan into this bad boy unless you widen the chassis by at least 10mm, but you can definitely get a pair of 140mm intakes in if you redesign the front, and those would help tremendously. The Define Mini is practically screaming for an R2.

Until Fractal Design comes up with a Define Mini R2, you're going to have to be okay with the trade-offs inherent to this version of the Define Mini. Alternatively, you may want to wait for Corsair's impending Obsidian 350D and see what they're planning to bring to the table where micro-ATX is concerned. The Fractal Design Define Mini isn't a bad case, but it does need some tender loving care, and it's not as great as it could be. It's the only micro-ATX case designed for acoustics, though, and if that's what you're looking for, the Define Mini's about the best option on the market.

    My TJ08-E is still quite loud, even on the fan's low setting.

    I've done 6 builds with the TJ08-e. For every one of them I have found the front intake fan to be too loud even on the low setting. Plugging into a motherboard with fan speed control helps, but can also cause the front fan to stop spinning at times.

    At home, it is an extremely audible case.

    At work, I can't hear the thing at all even sitting right next to me.

    That is the extent to which ambient noise is a factor. People that call this case quiet may be dealing with higher ambient noise.

    I think after 6 builds I feel pretty confident that I know the typical acoustic character of the TJ08-e

    Also, the drive cage in the TJ08-e is a serious drawback. None the less, it remains my go-to mATX case.

    I've done 4 builds with the TJ08e. I agree they aren't silent, but none of my builds turned out particularly loud either. While ambient noise can be a factor in the perception of what is quiet, I think this may be a difference in standards of quiet. In my most recent build with the TJ08e, the Zalman 9900CNPS is the loudest component. By my standards, the 9900CNPS while not silent, is quiet. The ambient noise environment shouldn't make a difference as to which component is loudest in the build, so if you find the 9900CNPS comfortable, then the TJ08e has the potential to work for you. Just don't expect it to mute louder internal components given it has no acoustic padding.

    I should mention that I forgo the HDD cage all together and mount a single SSD in the bottom bracket that the HDD cage mounts on top of. It makes a difference to airflow. Might make a difference acoustically as well.

    That is exactly what I did with my build, with my secondary HDD up in the 5.25 bay. No sound/temp issues at all.

    I have a TJ-08E, it's nearly silent in my very quiet home environment. I use the "full speed" setting of the switch (so it has enough voltage to start), and then put it down to 400-500 RPM with FanXpert control of my Maximus V Gene. Still plenty of airflow and totally silent.

    I'm pretty sure Dustin's tolerance for noise is a bit higher. I wouldn't call the low setting quiet at all. As for undervolting, you don't need to weld or use a resistor, all you do is the 5v,7v,12v trick of swapping molex wires cables.

    Yes, I have the fan on the low setting, it is still way more audible than a Fractal Design case.

    Meh. I know they had to do it to fit in the drive racks the way they have them but once again this is a micro ATX case that's a scant few inches smaller in one dimension than mid-tower ATX cases. I just don't see the point. If you really want a compact case there *will* be real compromises, tight fits, and less easy assembly than wide open ATX cases. But any 'micro' ATX case that's got a dimension of around 20" is just missing the point of micro ATX.
